Document Summary

There are at least three reasons why understanding genetic and chromosomal disorders are important: The role of genes and chromosomes in heredity. At the time of conception, when the sperm from a male unites with the ovum from a female a single cell known as zygote results creating the blueprint of the person. It eventually duplicates itself over and over until it becomes a living organism with its unique characteristics. Each of these is involved in different types of cell divisions. The stricture of all cells is the same (page 95) as they include a cell membrane (surrounds the cell matter or cytoplasm) in the cytoplasm there is the nucleus surrounded by the nuclear membrane. The nucleus is viral to hereditary as it includes the chromosomes on which the genes are located. Genes are considered the basic/smallest unit when it comes to hereditary. The genetic blueprint is known as a genotype. Chromosomes are made up of strands of dna.
